Abstract
The climatic conditions of the North have been forcing the human body to use additional social and biological means of protection against the adverse effects of environmental factors. It should be noted that, first of all, the cardiorespiratory system undergoes the influence of these abiotic factors. In this regard, the purpose of the research was to study and identify the characteristics of the cardiovascular system in young male residents of Magadan Region who differ in terms of residence in the northeast of Russia. 1632 young male subjects aged 17 to 21 and permanently residing in the city of Magadan, were examined in 2005–2017 using standard methods for determining cardiovascular parameters. Depending on the length of residing in the region all the subjects were divided into 4 groups. They represented three generations as well as migrant Caucasians who were not born in Magadan Region but came there from the central regions of the country. Residents of the northeast of Russia with short periods of residence in the North demonstrated a state of stress in the cardiovascular system manifested by an increase in systolic pressure, total peripheral vascular resistance, heart rate, and a decrease in the blood stroke volume. At the same time, the representatives of the 3rd generation had better functioning of the system. They were significantly lower in blood pressure (both systolic and diastolic) and the heart rate. In addition, the subjects of this group had minimal cardiac output, which indicated a more economical functioning of the cardiovascular system in the conditions of the northeast of Russia.
